On-line monitoring technique is applied successively in each power grid in the whole nation, though video monitoring is mature technology, also below generally existing
Problem：(1) need operator on duty continual on duty, supervise computer screen, to find whether in the video or photo passed back
Find out possible external force destructive factor.(2) traditional video surveillance device, is only equipped with a camera, can only shoot one mostly
The field image in direction, practical effect are bad.(3) single device cost is excessive, and needs the track section monitored very
It is more, cause the presence of the blind area much monitored.
By theory analysis it can be found that equally including the position of outer broken hidden danger in the output signal of interferometer and shaking
Dynamic information, therefore after positional information is removed, can utilize whether the amplitude of residual signal continues to exceed the warning threshold values of setting
To determine whether there are outer broken hidden danger.However, if only judging according to the amplitude size of residual signal, it will produce higher
False alarm rate.That is because circuit is distributed in very wide region, can occur many do not have prestige to line security near circuit
The behavior of the side of body, if the amplitude size of simple basis signal judges to will result in false-alarm.Therefore, interferometer is further handled
Demodulated signal, identify destruction type, system is correctly sent warning information and timely processing accident have it is important
Meaning.
